Excessive drinking and smoking, poor diets, stress and sedentary lifestyles account for 44% of China's incidence of cancer and heart and respiratory diseases, state media said, citing a new survey by local experts. With one-third of Beijing's populace suffering from unhealthy lifestyle diseases, the survey says the findings suggest that China is moving from the status of a developing country to a developed one, where 70-80% of heart disease and cancer deaths are caused by unhealthy lifestyles.
